📦 Examples
Full Example
import React from "react";
import setupIndexedDB, { useIndexedDBStore } from "use-indexeddb";
// Database Configuration
const idbConfig = {
databaseName: "fruity-db",
version: 1,
stores: [
{
name: "fruits",
id: { keyPath: "id", autoIncrement: true },
indices: [
{ name: "name", keyPath: "name", options: { unique: false } },
{ name: "quantity", keyPath: "quantity" },
],
},
],
};
const Example = () => {
useEffect(() => {
setupIndexedDB(idbConfig)
.then(() => console.log("success"))
.catch(e => console.error("error / unsupported", e));
}, []);
const { add } = useIndexedDBStore("fruits");
const insertFruit = () => {
add({ name: "Mango 🥭", quantity: 2 }).then(console.log);
};
return <button onClick={insertFruit}>Insert</button>;
};
export default Example;
add(value, key?)
Inserts given value
record to selected store, second param is optional key useful if auto-increment is disabled
By default commit is enabled after each transaction so changes are reflected in indexedDB instantly
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { add } = useIndexedDBStore("fruits");
const onClick = () => {
add({ name: "Mango 🥭", quantity: 2 })
.then(d => console.log(`Added Fruit with ID ${d}`))
.catch(console.error);
};
return <button onClick={onClick}>Add</button>;
}
getByID(id)
Retrive record by ID
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { getByID } = useIndexedDBStore("fruits");
const onClick = () => {
getByID(1)
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Get - ID 1</button>;
}
getAll()
Retrive all records from provided store
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { getAll } = useIndexedDBStore("fruits");
const onClick = () => {
getAll()
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Get All Fruits</button>;
}
getOneByKey(keyPath, value)
Retrives single record if any row matches with given keyPath
having value
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { getOneByKey } = useIndexedDBStore("fruits");
const onClick = () => {
getOneByKey("quantity", 2)
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Get Fruit w/ Qty 2</button>;
}
getManyByKey(keyPath, value)
Retrives multiple records in form of array if row matches with given keyPath
having value
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { getManyByKey } = useIndexedDBStore("fruits");
const onClick = () => {
getManyByKey("quantity", 2)
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Get All Fruits w/ Qty 2</button>;
}
update(value, key?)
Inserts or Updates given value
in store by ID
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { update } = useIndexedDBStore("fruits");
const onClick = () => {
update({ id: 1, name: "Strawberry 🍓", quantity: 20 })
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Update Fruid #1 to Strawberry</button>;
}
deleteByID(id)
Deletes record by ID
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { deleteByID } = useIndexedDBStore("fruits");
const onClick = () => {
deleteByID(1)
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Delete Fruit with ID 1</button>;
}
deleteAll()
Deletes all records
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { deleteAll } = useIndexedDBStore("fruits");
const onClick = () => {
deleteAll()
.then(console.log)
.catch(console.error);
};
return <button onClick={onClick}>Delete All Fruits</button>;
}
openCursor(cursorCallback, keyRange?)
You can use openCursor
to iterate over objects one by one within given keyRange
import { useIndexedDBStore } from "use-indexeddb";
function Example() {
const { openCursor } = useIndexedDBStore("fruits");
const onClick = () => {
openCursor(e => {
const c = e.target.result;
if (c) {
console.log(c);
c.continue();
} else {
console.log("that's all folks");
}
});
};
return <button onClick={onClick}>Open Cursor</button>;
}
